WASHBOARD.

Specification of Letters Patent.

Patented May 2, 1916.

Application filed March 31, 1914. Serial No. 828,521.

To all whom it may concern: a

Be it known that I, CLARENCE S. VVARREN, a citizen of the United States, residing at Milford, in the county of Clermont and State of Ohio, have invented new and useful Improvements in VVashboards, of which the following is a specification.

The purpose of the invention is theprovision of a washboard which admits of ready replacement of the rubbing plate when worn, thereby saving the expense incident to the cost of anew washboard which entails the cost of the rubbing plate and main frame.

In accordance with this invention the rubbing plate when worn may be readily removed and substituted by a new rubbing plate, such substitution adapted to be made by the average person without requiring the use of tools.

The invention consists of the novel features, details of construction and combination of parts, which hereinafter will be more particularly set forth, illustrated and claimed.

In the drawings hereto attached :-Figure' 1 is a front view of a washboard embodying the invention. Fig. 2 is a horizontal section on the line of Fig. 1, the dotted lines showing the manner of simultaneously removing a worn rubbing plate and back board after the fastener for the back board and rubbing plate has been removed, or the manner of placing a new rubbing plate and back board in position. Fig. 3 is a vertical section on the line g/@ of Fig. 1.

Corresponding and like parts are referred to in. the following description, and indicated in all the views of the drawing, by the same reference characters.

The frame of the washboard comprises side members 1 and 2, a cap piece 3, upper and lower cross pieces 1 and 5 and an upper rear board 6, which is secured to the rear edges of the cap piece 3 and the upper ends of the members 1 and 2. The space thus formed consists of the usual holder for receiving the soap which rests upon the upper cross piece 1. The cross pieces 4 and 5 have their extremities let into the side members 1 and 2 and are rabbeted to receive the upper and lower ends of the back board 7. The inner sides of the members 1 and 2 are grooved to receive the edges of' the back board. The groove 8 formed in the inner side of t e member 1 i deeper than the groove 9 formed in the inner side of the member 2, whereby provision is had for a lateral movement of the rubbing plate when removing the same or placing it in position. The groove 8 receives a vertical edge portion of the rubbing plate when placing the same in position and when the opposite vertical edge portion of the rubbing plate clears the inner side of the member 2 the rubbing plate is moved to the right a distance to admit of the same entering the groove 9, after which the rubbing plate is fixed by means of a fastening 10 which usually consists of a screw, the same being passed through an opening formed in the upper cross piece 1 and entering the upper edge portion of the back board 7 and passing through an edge portion of the rubbing plate which is bent so as to extend over the upper edge of the back board and enter the rabbet of the cross piece 1. The back board 7 has the edge portion adjacent the member 1 beveled as indicated at 11 so as to make provision for inclining the rubbing plate either'when removing or placing the same in position. The back board may be retained in place by suitable fastenings 12 which are placed in position after the parts have been properly arranged. The fastenings 12 usually consist of angle hooks the stems of which are threaded to screw into the back board. the bent ends engaging the rear edges of the members 1 and 2 to prevent outward displacement of the back board.

The rubbing plate 13 consists of sheet metal such as commonly provided in devices of this nature, said metal plate being fluted, corrugated or otherwise roughened to provide the projections essential to the rubbing surface of the washboard. The upper and lower edge portions of the rubbing plate are bent rearwardly at a right angle as indicated at 1 1 and 15. The upper bent edge 14: extends over the upper edge of the back board 7, whereas the lower bent edge 15 extends aoross the lower edge of such back board. The rubbing plate is of a width D sides of the members 1 and 2. When the rubbing plate is placed in position with its left hand vertical edge touching the inner wall of the groove 8 the right hand vertical edge of such rubbing plate clears the inner side of the member 2 and when the rubbing plate has been pressed close against the back *reater than the distance between the inner board 7 such rubbing plate is moved to the right to cause the right hand edge portion thereof to enter the groove 9, after which the rubbing plate is made secure by means of the fastening 10 in the manner stated. To replace a worn rubbing plate the fastening 10 is removed and the rubbing plate moved to the left until its right hand edge clears the inner side of the member 2 when the right hand portion of the rubbing plate is moved outward from the back board 7 after which the rubbing plate may be easily disengaged from the frame and a new rubbing plate substituted therefor.

From the foregoing description, taken in connection with the accompanying drawing, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which the invention appertains, and while I have described the principle of operation of the invention, together with the device which I. now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative, and that such changes may be made when desired as are within the scope of the invention as claimed.

Having thus described the invention, what is claimed as new is A washboard comprising a frame, including side members and upper and lower cross Gopies Of'thll patent may be obtained for five, cents each, by addressing the pieces, said side members having a longitudinal groove in the inner face thereof, one of: said grooves beingideeper than the other, a rubbing plate, a back board loosely connected therewith, said rubbing plate and back board being mounted within said frame, and toslide between the side members and upon theicross pieces to cause the vertical side edges of the back board and rubbing plate to enter the grooves in the side members, said grooves being of greater width than the combined width of the rubbing plate and back board to permit lateral movement of the back board and rubbing plate during the positioning of the board and plate Within the frame or the removal of the board and plate therefrom, hooks removably connected with the back board anu contacting with the side members when the back board is positioned within the frame to prexent'lateral or sliding movement of said board therein, and means carried by one of the cross bars for securing the rubbing plate to the back board and adapted to permit the removal of said rubbing plate from within the frame independent of the back board.

In testimony whereof I my signature in presence of two witnesses.
